                The statistics utility can be used to print out information on
                tables in a database.  A detailed description of the statistics
                utility is described at <a href="../api_reference/C/db_stat.html" class="olink">db_stat</a>
                  .  This
                section describes how to use the utility with a SQL database.
            </p><p>
                The first step in getting statistics on a table is to find the
                internal name for the table.  The internal table name is
                <code class="literal">table#####</code>, where the number is the rootpage
                number, which can be retrieved using the following SQL statement:
            </p><code class="code">
                SELECT rootpage FROM sqlite_master WHERE name='[table name]';
            </code>
                For example, if the root page is 10, the internal table name
                will be <code class="literal">table00010</code>.
            <p>
                In order to run the <span class="command"><strong>db_stat</strong></span> utility, 
                first add a <a href="../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a>
                     file to the journal directory.
                In the file, add the following line:
            </p><code class="code">
                add_data_dir ..
            </code><p>
                Then execute the following command in the directory
                with the database:
                <span class="command"><strong>db_stat -d [file name] -h [journal directory] -s [internal table name]</strong></span>.
                That command will print out information on the table.
